Some quick calculations...
At 6 oz/t and 50 tpd, that's 10 oz/day or 300 oz/month. At $1600 gold, that's about $500k/month, or half the burn rate. If they double the mill rate to 100 tpd, they're at breakeven. At 150 tpd, they're making $6M/yr. Off of waste ore. Before they start mining the good stuff.
